Abstract

Disclosed herein are a resin pipe, a process for production thereof, a base for a photosensitive drum, and a photosensitive drum formed from said base, said photosensitive drum being used for electrophotographic apparatus such as copying machines, facsimiles, and printers. The base has a tapered inner surface with a specific taper angle (). The base also has a projection formed at a specific position. The base is formed from a specific molding material.
